How did mendeleev make predictions about the properties of elements?

This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded.
For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.

What important scientific discovery did dimitri mendeleev make about materials?
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
Can you predict the properties of a compound by knowing the properties of the elements that make up the compound explain your answer?
No because the elements that make up the compounds have different properties than the compound's properties.
Who created the periodic table?
The first periodic table was developed by Dmitri Mendeleev in the mid-19th century.He wasn't the only person thinking along those lines ... both John Newlands and Lothar Meyer had proposed similar ideas However, Newlands was largely criticized and ignored at the time, and Meyer didn't make any predictions, so Mendeleev's table (which did make predictions about the properties of several as-yet-undiscovered elements) is generally regarded as the first.
How do the properties of a compound compare with the properties of the elements that make up the compound?
Compounds have different properties from the elements that make them. ... The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged.
Why was mendeleev unable to make any predictions about the noble gas elements?
The reason that Mendeleev didn't make any predictions about the gases was that these gases were not even discovered yet, therefore it was impossible for Mendeleev to make predictions.----Dmitri Mendeleev made his predictions on what would fill the gaps on his far from perfect periodic table. He predicted their sizes, weights, appearances, etc.I think the reason he didn't make predictions is because noble gases are not visible, and weightless.-------------------------------Mendeleev couldn't predict the noble gases' properties because their existence wasn't known, as implied above.Argon, a noble gas, was noticed twenty-five years later by John William Strutt and Sir William Ramsey (the names are not really important).It doesn't matter that the elements weren't discovered. That's the whole point of arranging the elements. To PREDICT the properties of the missing/unknown ones.
What kinds of predictions did Mendeleev make using his table?
By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
Why was Mendeleev's periodic table widely accepted?
Mendeleev ordered the elements according to increasing atomic mass in vertical and horizontal rows. The horizontal rows contained analogous elements. This system was clear and consistent, and was superior because the number of protons, the most massive particle in atoms, is actually what distinguishes each element.
Why were Mendeleevs efforts on the peridic table more successfully the other scientist?
Mendeleev's table was more systematic. Elements were arranged in order of atomic masses.
How Mendeleev used the data available to him to create his periodic table?
Mendeleev placed his elements in order of increasing atomic mass. He placed elements with similar chemical properties in the same groups or families. He realized that there were some gaps in the table where an undiscovered element should go and made predictions about those elements before they were found.
Which were the elements predicted by Mendeleev and what name did he give them?
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)
What did the Russian scientist Mendeleev create the periodic table?
your question does not make sense. your question does not make sense.
What scientist before mendeleev developed the first ideas of arraging the elements?
Johann Wolfgang Dobereiner arranged them in triads, Alexandre-Emile Beguyer de Chancourtois arranged by atomic weight, John New-lands and William Olding published periodic tables that used atomic weight to arrange the elements into groups with analogous properties, Julius Lothar Meyer is closest to periodic table as it is today he just didnt make predictions about unknown elements like Mendeleev
What important scientific discovery did dimitri mendeleev make about materials?
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
What is the process mendeleev used to make the periodic table?
He made flashcards of elements and organized them in order of increasing atomic mass.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
What does the statement the properties of salt are different from the properties of the elements that make them mean?
he properties of salts are different from the properties of elements that go into making them
